"we don't know anything about the mk1 ferret finder"
says it all doesn't it.
i tried to ask about how to re calibrate 2 clollars i just got to my original box, and they told me they know nothing about them, i asked if they knew of anyone who could help me and was told the best thing to do was by the mk3m.
there has got to be someone on here who knows how to calibrate them or knows how to track down someone who used to work for deben, to say how long the mk1 has been around and how many people own one there seems very little knowledge on them.
any help appreciated
